Abstract (en)

[origin: US2018234721A1] A method for removing transitional noise in an audio data stream is performed by a computing device. After obtaining first and second audio frames in a time sequence of the audio data stream, the computing device determines a frame segmentation position in the audio frames based on predefined closeness criteria that require a predefined distance between the sampling point values at the frame segmentation position in the first and second audio frames to satisfy a predefined closeness condition. Next, the computing device obtains respective sampling point values preceding the frame segmentation position in the second audio frame and ones following the frame segmentation position in the first audio frame. The computing device then sequentially stitches the respective sampling point values obtained from the first and second audio frame to generate a third audio frame and inserts the third audio frame between the first audio frame and the second audio frame.
